题目内容
3.If I _______ him not to do so,he wouldn't have made such a serious mistake.( )A. | persuaded | B. | would persuade | C. | had persuaded | D. | should persuade |
分析 如果我已经说服他不要那么做的话,他就不会犯这么严重的错误了.
解答 答案:C
根据句意可知,该句是虚拟条件句;由于主句使用了would+have+done的形式,因此此处表达的应是与过去事实相反的假设,所以if从句应使用过去完成时(had+done);故选C
点评 本题考查了过去完成时在虚拟条件句中的用法.做本题时,需要熟练掌握在虚拟条件句中,关于时态对称的用法.
